Clarified and standardized apple juice was ultraviolet-irradiated to inactivate polyphenol oxidase enzyme and microbiota, and its effect on bioactive compounds and stability during storage was also evaluated. Apple juice was irradiated with 345.6 J/cm² and treatment effect was evaluated in terms of color, antioxidant capacity, polyphenol content, pH, titratable acidity and total soluble solids....
Terminal buds of dark-grown pea (Pisum sativum) seedlings have an indole-3-acetic acid oxidase which does not require Mn(2+) and 2,4-dichlorophenol as cofactors. Oxidase activity is at least 50 times higher in buds of tall peas than in dwarf seedlings. Administration of gibberellic acid to dwarf peas stimulates both growth and indoleacetic acid oxidase activity to the same levels as in tall see...
objective: determination and comparison of the effect of infusion time on the antioxidant activity and total polyphenol contents of bagged and loosely packed black teas. materials and methods: for twenty loosely packed and eleven bagged tea samples, the antioxidant activity and total polyphenol content were analyzed using frap and folin-ciocalteau methods, respectively. the anova with tukey pos...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
Drought and changes in weather conditions, cause damage and reduce their agricultural products. The fact that durum wheat, after common wheat or Simultaneous with that, is one of the major sources of food supplies, makes it a necessity to identify its drought tolerant species.This article reports an experiment on the impact of different levels of drought ( 5,10,20, 25 percent of field capacity)...
It is reported that chlorogenic acid is widely distributed in plants (7) and is the principle polyphenol in tobacco leaves (8). When the tissues of the tobacco plant are injured, the polyphenols are oxidized and then polymerize, forming a brown pigment. This oxidation is reported to be catalyzed by polyphenol oxidase. Polyphenol oxidase has been identified in many species of plants and the enzy...
to find out the effect of sodium nitroprusside (snp) in reducing oxidative damage induced by salinity stress in barley seedlings, a crd based factorial experiment with three replications was conducted in agronomy laboratory of the faculty of agricultural sciences, university of guilan, in 2012. the experimental design consisted of two snp levels (0.1 and 0.2 mm snp; as nitric oxide (no) donor) ...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
Ascochyta blight caused by Ascochyta rabiei (Pass.) Labrousse is a major biotic constraint in production of chickpea. In the present investigation, all chickpea genotypes [E100Y (m), Gaurav, Pb-7 and L550] induced 100% callus on standard medium with greenish colour and fragile structure. These calli were used for in vitro screening against pathogen, A. rabiei culture filtrate at 0, 5, 10, 15 an...
